It already has collapsed. Doesn’t matter whether I hope it does or not. Their own dysfunction has brought about its collapse. It’s sad, but they only have incompetent and criminal leadership for 32 years to blame.
As for America, we need to stay out of foreign conflicts. There is literally no reason for us to be involved in a civil war between the Ukraine and Russia. Israel can also handle itself, too. If there are American hostages in a foreign locale, that would make it our business, but only in that instance.
NATO needs to be disbanded, as a warmongering globalist enforcement arm. It completed its assigned mission in 1991. Thankfully, it appears President Trump will remove us from it, which will force Europe either to financially sustain it or end it.
(1) To avoid having the world become led by nations hostile to American national security;
(2) To maintain the value and attractiveness of the US dollar as the global reserve currency, which permits us to finance our massive public deficit due to spending on Medicare, most of all;
(3) To protect American trade and economic interests and to have access to the world's resources; and
(4) To keep in check nations (Russia and China) that have nuclear weapons that could utterly destroy the US and its allies within a matter of hours.
Saying that Russia and Ukraine are in a "civil war" presupposes that Ukraine is inherently a part of Russia. That is simply untrue, historically or legally. Indeed, at the end of the Cold War, Ukraine gave up its stock of Soviet nuclear weapons in return for assurances from Russia, the US, and the UK that Ukraine's independence would be honored and protected.
As for what you refer to as Ukraine's dysfunction, it is a far better place than Russia, a dismal nation run by gangsters.
